Yes, over 10 years ago I made a scramble net for my Graupner Wiesel (scale: 1/40). I made it by starting with a flat piece of woo, marking off a grid to the size I wanted it to be. Next I put in some brads (small nails) along all sides then weaved and knotted the lines. Finally, I added the round disks to the sides that keep the net away from the hull for safer climbing.
There are plenty of references for full sized nets (even how to tie the knots) including this one:
